B82789C0223N002

Overview

The B82789C0223N002 is a surface-mount data line filter manufactured by EPCOS (TDK). It features two functions with an inductance of 22 µH and a rated current of 0.25 A. The component supports a maximum voltage of 80 V DC and operates within a temperature range of -55 °C to +125 °C. Its physical dimensions are 4.5 mm in length, 3.2 mm in width, and 3.0 mm in height. The device exhibits a maximum DC resistance of 0.58 Ω and an output impedance of 50 Ω.

Feature Summary

• Designed for data and signal line filtering applications
• Compact surface-mount package suitable for automated assembly
• RoHS compliant construction

Applications

• Data line protection in electronic circuits
• Signal line choke applications
• Common-mode noise suppression in communication interfaces

Procurement Notes

Verify the specific suffix code against official TDK/EPCOS documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with RoHS directives if required by your manufacturing standards. Cross-reference the manufacturer's latest datasheet for any updates on lead content or material composition declarations prior to final procurement decisions.

Selection Notes

Select this component when a compact, high-reliability filter is needed for data lines requiring 22 µH inductance. Consider the 0.25 A current rating and 80 V voltage limit during circuit design. The small footprint makes it suitable for space-constrained PCB layouts where standard through-hole components cannot fit.

Part Context

This part belongs to the B82789 series of data and signal line chokes from EPCOS (TDK). These components are engineered for common-mode noise reduction in high-speed data transmission environments. The series offers various inductance values and current ratings to suit different interface requirements while maintaining a consistent surface-mount form factor.

Replacement Considerations

Consult official substitution lists for equivalent parts within the B82789 series or compatible TDK product lines. Verify that alternative components match the 22 µH inductance, 0.25 A current rating, and 4.5x3.2x3.0 mm package dimensions to ensure mechanical and electrical compatibility.
